To all whom it may concern/.-

Be it known that I, JOSEPH A. Snmns, a citizen of the United States, residing in the city and county of- Denver and State ofColorado, have invented certain new and useful Improvements in Train-Ventilating Apparatus; and I do declare the following to be a full, clear, and exact descr'i'ptio'n'of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form apart of this specification.

My invention relates to improvements in ventilating ap aratus for trains and includes features for fi tering the air introduced for ventilating purposes, whereb it is deprived of all impurities, as dust, smo e, cinders, and other foreign. elements, which, particularly during certain seasons of the year, are exto passengers on cars as now constructed. i

My im roved ventilating apparatus also includes eatures whereby the air may be temperedthat is to say, either cooled or warmed-aclcordin to the requirements, which of course wil depend to a large extent upon the changeo'f seasons. It is assumed that during the summer or hot season it may be necessary to cool the air, while during the winter or cold part of the year-it willbedsirable to raise 'the normal temperature. In my 1mproved construction provision is made for conducting the air from one car to another of the train, and to this end flexible conduits or airfducts are: employed, the flexibility being such as to com ensate for the variation in the position of t e train resulting from its lateral or swinging'movement, as well as its longitudinal or len thwise vibration. The length of the flexi le features of the ducts or conduits may correspond a proximately with the width of the flexible vestibule portions 'of vestibuled trains.- The adjacent members of'each conduit are connected in such a' manner that if the train breaks or the cars separate the duct or conduit' members will separate automatically without injury- In coupling their extremities are simply pressed together, and the yielding or spring features maintain the connection" under ordinary circumstances.

Having briefly outlined my improved conis illustrated an embodiment thereof.

In thedrawings, Figure 1 is a side elevation of a train composed of a number of cars equip ed with my improvement. Fig. 2 is a side e evation of a car, artly broken away and partly sectionized equipped with my improvements. It is'assume that this is the foremost car of the train, ordinarily the baggage, mail, or express car.

In this view.the construction is shown on a scale somewhat larger than in Fl 5. 2 and 3. Fig. 5,is a longitudinal section 0 one of the funnel-shaped air-gatherin devices. 'Fi .6 is a sectional view taken lfiirough the a jae cent extremities of two cars equipped with my improvements and showing the air-ducts in connected relation. Fig. 7' is a fragmentary rear end view of the rear car, showing the outlet for the air from the train. Fig. 8

Fig. 11 is an enlarged elevation, partly in section, illustrating the juncture of the several branches of the airconduit in the form of construction employed with a dining-car. Fig. 12 is a sectional view taken through the air filteringand tem pering apparatus.

The same reference characters indicate the same parts in all the views.

Let the numeral 5 designate the individual cars of a train. The front car, or the one nearest the locomotive, is equi ped, prefer- Fig. 3 is a front end elevation of the same being being "arranged one above another, the uppermost device on each side occupying a position on the roof of the car. Each funnel 6 terminates at itssmaller extremity in a pipe 4, leading to a casing 8, with which a large pipe 9 communicates and through whichthe air passes to a main conduit 10.

It must be assumed that each side of the car is equipped as shown in Fig. 2 and that the branch pipes 9 on each side curve inwardly, as indicated at 9 and merge into or are suitably connected with a suitably-located pi e 10. The body portion of the pipe 10, as s own in the drawings, passes below the bottom of the car, while its rear extremity extends upwardly through the bottom of the car and enters a casing 12; (Best illustrated JD Fig. 12.) This casing is covered on the outside with a canvas or other suitablyabsorbent material 13, adapted to be saturated with water supplied by a conduit 14, provided with a valve 15. This conduit has a downwardly-directed nozzle 16, through which water may be delivered to the top of the casing, whereby it is allowed to run downwardly and saturate the absorbent covering 12. This water will have a tendency to cool the air which enters the casing.

The bottom of the casing is provided with a drip-trough 17, having an outlet or'waste pipe 18, leading downwardly through the bottom of the car, for the escape of the drip collecting in the trough 17, into which the water from the absorbent coverin 12 drains. Within this casing is located a hlter 18, composed of flexible mesh material. The bottom of this filter is connected with a flange 19, secured to the inside of the casing and surrounding an openin which, the bottom of the filter enters., The ottom' of the filter is detachably connected with this flange. As shown in the drawings, the flange is provided with a downwardly-bent portion 20. ,The bottom of the filter-cloth is turned upwardly around the portion 20 and held in place by a removable spring or other suitable device 21, whereby the filter is readily detachable. The top of the filter-bag is closed, as shown at 22, and passes upward y through the center of a steam-coil 23, which may be employed to warm the air when its normal temperature is too low for use.

This closed upper extremity of the filter-bag is connected with a cor d 24, passing over'pulleys 25 and 26 and thence outwardly and downwardly, its lower extremity being provided with a hand piece 27. This cord enters a slot formed in a ledge 28, connected with the filter-casing. By removing the cord from the ledge 13 the top of the filter-bag may be raised and lowered for the urposeot shaking out the 1 ipuritie whic have collected during the peiiormance of its function. These impurities may he collected in the bottom of the and moved through an opening 29, which may ,esaes'e controlled in any suitable manner. Access is gained to the casing about midway by redrawings, is held in place by fastening devices 31. i

The pipe or conduit 10 below the car is provided withan opening surrounded by a dc ending nipple 32, normally closed by a va ve 33. This valve is fulcrumed at 34 and is provided with a weight, as shown at 35, of suflicient size to normally hold it in the closed position. The valve is fulcrumed on a hanger 36. To the weighted extremity of 37, which has a cord, wire, or rod whose upper extremity is provided with an eye 38, ada tedto engage a su porting device 39. he car is provided wit a series of these devices 39. When-it is desired to open the valve 33, it is only necessary'to pull upwardly on the device 37 and connect its eye with; one of the upper supports 39. This valve-opening is important, since it provides means for the removal of any water which'may have entered the funnel 16 by reason of-snow or rain. it may also be employed to remove forei matter which may have collected within t e ipe 10 and which mayhave entered the same y way ofthe funnel 6 or from the filter-casmg.

The top ofthe filter-casing is provided with a short outlet-conduit 40, which communicates with the casing and passes outwardly to the rear end of the car, as shown at 41. To this outwardly-protruding part of the conduit 40 is connected a flexible conduit or duct 42, to whose outer extremity is applied a band 43, having locking devices 44, provided with short projections 45. This flexible conduit member 42 issupported by an overhanging arm 46, one extremity of which is connected with the roof of the car, while the other extremity extends above the end of the car and is provided with a hook 47, over which an eye 48, connected with the flexiblemember 42, is passed. The bands 43 of the flexible members are each provided with one'or more locking devices 44. It may be assumed that there is an equal number of these locking devices on each band, each band being also provided with openings'adapted to receive the short projections 45. I

The flexible member-'42 of'the rearmost car should be provided with aclosure 49.

, i .L, u .c in and the escape 0.1

; through he passed 0 unoving a closure 30, which, as shown in the,

This closure may be readily removable,

the valve is attached a manipulating device In the coaches in the rear of'the foremost car the air is discharged into the upper part of the car, as shownin Figs. 6 and 8, the exterior duct 42 communicating with an interior nozzle or extremity 52. The air is discharged into the upper part of the car at one extremity to a nozzle 52 and escapes from a correspondin nozzle 52 at the opposite extremity of t e car. This arrangement induces a longitudinal current in the upper part of the car, which current produces sufficient suction to remove the impure air of the car. Enough of the air which enters the top of the car moves downwardly therein to take the place of that removed by the suction resultin from the upper current.

In t ecase of the diningcar (shown in Fig. 9) the construction and arrangement is somewhat different. In this casetherc is a ipe or conduit 53, extending from one end of the car to the other and communicating with nozzles 54 at the opposite extremities of the car, which nozzles are connected with the exteriorly located flexible conduit members 42. The pipe 43 also communicates at the op 0- site extremities of the car with verticallyisposed pipes 55, which lead into ice-boxes or other receptacles 56. The lower extremities of these vertical pipes are open. At the junction of the ipes 53 and 55 a damper 57 is located, whic may be adjusted to allow a portion of the air to enter the downwardlyextending pipe 55 at the end of the car where the air enters at its forward extremit There is also a similar dam er located at t eo posite extremity of t e car. 1 It is evi ent, however, that a portion of the air which enters at the forward extremity of the car, assuming that the damper is open or in the-position shown in Fig. 11, will pass downwardl through the pipe 55 and be discharged into t e car. The current, however, passing through the upper conduit 53 will produce more or less suction in passing over the upper extremity of the pipe 55 in the rear and, it is believed, draw air from the rear extremity of the'car, thus allowing the impure air to escape. In Fig. 9 the partition 58 separates the cooking-compartment 59 of the diningcar from the guest-compartment.

Referring to the steam-coil 23 in the upper part of the filter-casing, the exteriorlylocated pipe 59 may be termed the inlet and the pipe 60 the return or outlet therefrom.

Erom the foregoing description the use and operation of m improved train-ventilating apparatus will e readily understood.

Referring to Fig. 1 of the drawings, it is assumed that a train e qui ped as shown is moving toward the right. ment the air to be employed in ventilating the cars enters the funnel-shaped devices 6' and passes thence into the conduits 9 and therefrom into the main conduit 10 and uring this movecar into the filtering-bag 18, located within -the casing 12, where all impurities are strained out or removed therefrom. The air passes through the mesh of the bag and outwardly through the conduit members 40 and 41 and thence into and through the flexible members 42 between the cars and thence I into the next car, which it may be assumed is a coach or Pullman occupied by passengers. The air enters the upper extremity of the car, producing a current through the car to the esca' e-nozzle 52, through which the impure air om the car passes out. Enough of thepure air which enters the car remains to take the place of. the impure air which es capes- This operation is continued until the air-current escapes at the rear extremity of the rearmost car. The only change of operation is in passin through a dining-car, where a portion of t e air is allowed to pass downwardly into the car, while another portiondpasses through an inclosed conduit 10- cate in the upper part thereof.

While my invention is more especially intended'for use in connection with passenger trains, it is evident that it may be em loyed to advantage in'connection with freig '-cars containing classes of freight requiring special ventilation, as where it is necessary or desirable to exclude the dust,'dirt, and cinders which ordinarily enter cars of all classes through the ventilating-apertures.
